This seems bad. I hope this problem will get addressed soon. Sounds like you cannot apply a negative offset to this CPU and thus you cannot undervolt this CPU. Undervolting is the most important feature if you want to bring temperatures down with very little performance loss. So hopefully the will be an update for your board.There is a bios issue for me on 5800X3D- B550 Gaming Plus - 7C56v1B.
The offset voltage applies a positive offset to the CPU instead of a negative one ( French MSI SAV said you don't use the right bios for this cpu... , so they probably won't forward the issue).
And i'm also quite sure there is an issue with the ERP ready which seems to be always ON (no power to USB when set to OFF). This was working fine when I was with my 3700X - Bios 7C56v17
